If I have some spare time, I will try to write up more details, but I am
not sure whether the tlmgr man page is the correct place.

Wellm these are conceptionally two different things: The one controls
whether checks should be made, the other controls whether missing
signatures should be treated as errors or not.
Thus there are more differences: With --no-verify-downloads, nothing is
done, and no gpg available or so is reported. While without it, the
signature status (no signature, missing public key, ...) is reported.

Indeed, there are a lot of components playing into, one being that the
logging of checksum was not done in all places :-((( Sorry for that.
The other thing was that the actual packages were only checked against
the sizes and not the checksum, due to some refactoring at some point
(renaming the checksum data from containermd5 to containerchecksum).
This has been fixed now in the subversion repository and will be pushed
out rather soon. Now with -v tlmgr would spit out something like this:
D:tlpdb:_install_data: what=/home/norbert/public_html/tlnet/archive/collection-latexextra.tar.xz, target=/home/norbert/tl/2017/texmf-dist, size=5504, checksum=6e72d01334e032e927d1ccc06e50766d6d151e20e6d6997a3c4e2950b73bc082bce773a946930b9db9ec20f323a88a2d242f0cb012998a258fc4244de546fb33, tmpdir=/tmp/UQNV4diBME/lzqy7LKVuv

Big thanks for your insistance which pointed me at insufficiencies *and*
bugs in the code!!!!
